Night-time restrictions to safeguard the water supply for customers supplied by Cairnhill reservoir

06 July 2021

Reservoir low due to major leak

Uisce Éireann and Longford County Council wish to advise customers supplied by Cairnhill reservoir that essential overnight water restrictions are required from tonight Tuesday 29 June until the morning of Saturday, 3 July to allow the reservoir to re-fill. The restrictions will be in place nightly from 11pm until 7am. While water will be turned back on at 7am each morning it may take up to 2 hours for supply to be fully restored to all areas fed by the Cairnhill reservoir.

Major leak

A major leak on the network has caused the reservoir levels to drop significantly and it will take a number of days for levels to recover. Crews are working to carry out the repairs to the watermain as quickly and as safely as possible. The restrictions are necessary to allow reservoirs to refill so that essential daytime water supply can be maintained.

Conserve water

We are asking customers in these areas to be mindful of how they use water. However it is important to continue to follow the HSE guidance on hand washing. While handwashing remains a priority, simple water conservation efforts can have a big impact on reducing demand on the supply. Turning off the tap while brushing your teeth and shaving can save up to 6 litres of water per minute. Taking a shower instead of a bath or using a watering can rather than a hose when gardening can also make a big difference in water use. We are also reminding people with responsibility for properties that are currently unoccupied to check for leaks and turn off water where it is not required.
